Below is the code to do it in vtd-xml  It basically queries the XML with the XPath of   xml item  name    import com ximpleware     public class getAttrs      public static void main String   s  throws VTDException           VTDGen vg   new VTDGen             if   vg parseFile  input xml  false      turn off namespace               return           VTDNav vn   vg getNav             AutoPilot ap    new AutoPilot vn            ap selectXPath   xml item  name             int i 0           while   i ap evalXPath     -1                 System out println   item name is     gt   vn toString i 1
